Postextraction Socket Seal Surgery with an Epithelized Connective Tissue Graft Using a Subpapillar Tunneling...

Ridge preservation in the esthetic area is still a challenging procedure. The aim of the present case series was to introduce a technique for postextraction socket seal surgery using an epithelized connective tissue graft and socket filling with a xenogeneic biomaterial. Using a tunneling approach, the buccal gingiva and interdental papillae are undermined and augmented with the soft tissue graft. This method was applied and evaluated in 16 sites in 13 patients with need for extraction of at least one maxillary anterior tooth. Five months postoperative, the mean reduction of the horizontal width of the alveolar ridge was 0.5 mm, while the height of the mesial and distal papillae were reduced by 0.2 mm and 0.4 mm, respectively. The buccogingival margin of the alveolar ridge showed a vertical gain of 0.5 mm. Therefore, the presented technique seems appropriate for preservation of the alveolar ridge in esthetically relevant areas.
